A process for preparing solid ammonium phosphates as defined in the specification, which comprises reacting phosphoric acid containing less than 60% P2O5 with ammonia gas under superatmospheric pressure to give a fluid solution of ammonium phosphate at its boiling point containing 4% to 15% by weight of water and subsequently expelling the resulting ammonium phosphate solution to an area at ambient pressures, thereby reducing its water content and yielding a solid product.
